I wish I could buy gold-plated copperclad... the copper looks great

would plate some copperclad for us. THAT would look classy.
Clean and shine it with Brasso, rinse well, rinse with isopropyl, rinse
with acetone (if you don't have any aceton-vulnerable parts), dry
thoroughty, and spray with Krylon.
That'll leave an awful stench next time you make a change.
The krylon is acrylic - it should come right off with a little acetone
or ethyl acetate. :-)
Yeah but who does that? People realize that R13 should really have been
to GND instead of Vref, flick on the Weller switch, phsssst ... "Hey,
Leroy, did your stogie roll onto the carpet again?"

Well, I wouldn't expect you to take a prototype that's not even done
yet, and dress it up for presentation! You don't lacquer it until it's
ready to go on display, silly. ;-)


Well, you know engineers, don't ya? There will always be last minute
changes, just like programmers aren't really done until the amount of
ROM is 99.5% filled ;-)

More than 99.5% filled. We had to do compression/decompression on the
last gadget we did, to fit 6 mbits of fpga config plus the application
code into a 4 mbit eprom. Not only did it work, but the fpga load got
faster!
